Two types of bis(β-diketonato) Co(II) complexes, [Co(CNacac)2] (CNacac = 3-cyano-pentane- 2,4-dionato), and [Co(dbm)2] (dbm = dibenzoylmethanato or 1,3-diphenyl-propane-1,3-dionato) were examined as linear building blocks for the construction of coordination polymers in combination with two oligopyridines, 1,4-bis(4,2':6',4'-terpyridin-4'-yl)benzene (L1) and 1,3-bis(3,2':6',3'- terpyridin-4'-yl)benzene) (L2). From combinations of [Co(CNacac)2] with L1 and L2, 2-D coordination polymers, [Co(CNacac)2]2(L1) (CHCl3)(CH3OH) (CoCN-1) and [Co(CNacac)2](L2)1/ 2(tetrachloroethane)3/2 (CoCN-2), are obtained. Both CoCN-1 and CoCN-2 have 2D (4,4) net structures, in which L1 and L2 are tetradentate. In contrast, combination of [Co(dbm)2] with L2 affords a 1-D coordination polymer, [Co(dbm)2](L2)4(CH3OH) (Codbm-1), in which L2 is bidentate. L2 as a tetradentate ligand was inhibited by bulky phenyl rings in [Co(dbm)2]. These results indicate that [Co(CNacac)2] with a relatively simplified structure is useful as a linear building block in combinations with bulky oligopyridines.

Paragraph 0041-0046, (2017/06/08)
PROBLEM TO BE SOLVED: To provide a novel terpyridine derivative as electron transport materials for organic EL elements that can improve electron transport properties while maintaining high triplet energy, and emits green phosphorus light. SOLUTION: The present invention provides a terpyridine derivative represented by formula (1). It is very effective as electron transport materials because it makes its skeleton planar by intermolecular hydrogen bond, and has intermolecular interaction at a terpyridine site (As independently represent a substituent represented by the following structural formula).
